Try the code below ~
function showPopup(current,evt)<br />
{<br />
var id;<br />
var x;<br />
var y;<br />
id = current + "popup";<br />
if(window.event){<br />
x = event.clientX + top.document.body.scrollLeft;<br />
y = event.clientY + top.document.body.scrollTop - 40;<br />
}<br />
else{<br />
var e = (window.event) ? window.event : evt; <br />
if(e != null){<br />
x = e.clientX + top.document.body.scrollLeft;<br />
y = e.clientY + top.document.body.scrollTop - 40; <br />
}<br />
}<br />
top.document.getElementById(id).style.display = "block";<br />
<br />
if((x == 'NaN') || (y == 'NaN')){<br />
top.document.getElementById(id).style.left = x + "px";<br />
top.document.getElementById(id).style.top = y + "px";<br />
}<br />
}<br />
<div id="control" onmouseover="showPopup('control',event)" onmouseout="hidePopup('control')"

The window.event property only exists in Internet Explorer. Other browsers send the event object as a parameter to the method that handles the event.

Would you know were I could find an example of the other browsers sending the event object as a parameter?

Hoping someone can help me here, I'm uncertain if this is a VB problem or a problem with the WebBrowser control. I have a simple testharness and html page that the WebBrowser hosts.
When you run the test harness and press the ShowDlg button, the WebControl form (Form2) opens where you can happily choose values from the html dropdown in the WebBrowser using the mouse (or keyboard) - ok. However if you activate mouse hooking by pressing the Hook button first, when you then activate the WebControl form, you can no longer use the mouse to select options from the dropdown, you can open it and hover over options but if you select something with the mouse, the previous value is retained - the mouse hooking seems to interfere? Also, if the dropdown has vertical scrollbars, the mouse doesn't seem to work on that either? You can however select options from the dropdown using the keyboard.
Taking this a little further, the "Pass Msgs On" checkbox can be unchecked. This stops the call to CallNextHookEx (in Module1.bas) in the MouseProc which would mean as I understand it that the mouse messages this interrupts are no longer being passed on - however if you then goto the WebControl again, you'll see that we can now select options from the dropdown using the mouse? This to me would seem to work the opposite to how you'd logically think this would work - ie. swallowing the mouse messages you would think would cause the problems (if any), as you're not passing the messages on?
Any help/suggestions would be greatly appreciated! Hope I've explained this well enough - best use the code below to see the problem yourself.

Hi,
Can you plase give me a hint .... I want to load an image (jpeg) from the server generated by an aspx without postback, so i created an XMLHTTPRequest oject, I run the aspx, the responeXML is an XML and the image is base64 encoded inside a node... (i can see the string in my page) how can i display it ?
So i need someking of javascipt to decode it ? Am I on the right track ?
Thank you!
iulian.

No, I don't think so. I think the right approach here is to use AJAX to send down the path to the image, and then use javascript to set the properties of an IMG tag on the page.

it's ok what you say but i want the image to be dynamicaly generated based on user inputs so ... if i generate the picture and save it on disk and then send the link to the client to retrieve it i will have hundrads of useless generated pictures on the server ??
my ideea was to dynamicaly generate the picture and send it to the user (the actual data) ???
can i do that ?
thanks

If I understand what you are doing, problem is that you can't "write" picture into page. Pictures are NOT part of the page. What you need to do is generate your .jpg file on server, and using ajax set the image source to something like
<img src="givemepicture.aspx?picture" />
And givemepicture.aspx will write your image (probably generated using parameters passed in url) into its response. I don't know if the browser will automaticaly reload image after you change it's src with javascript.

In my site I have used ajax technology . What I want is to prevent the user from doing anything on the page while the data is being fetched from the server using ajax. I don't want the user to be able to click a link , etc . Is it possible to do it in one place . Any Idea ??

while processing, you should display one overlay image on the screen..
You can check the technique which is used in open source *box[^]

I start using the TreeView web control. I feel the default spacing between leaf nodes is quite big. I want to reduce the spacing so that I can fit more nodes. Is there a way to control the spacing(reduce to the min., rather than increase) ?
I have tried setting all "NodeSpacing" and "VerticalPadding" to 0px. The spacing is still too big for me.
Thanks in advance for any suggestions!

Hello. Here is my situation. I'm building a client asp.net application that will reside on our DMZ. I have a web service (called "ServiceBus") that acts as a single access point through a single port to our data center.
The ServiceBus has methods that do several tasks such as fetching data, running SSRS reports, streaming documents, etc. Everything works fine when testing my client app from within the domain but from the DMZ I get authorization errors (see subject line).
The following line of code will get me to the HelloWorld method but any other method that fetches anything from another server fails with permission errors:
serviceproxy.Credentials = System.Net.CredentialCache.DefaultCredentials
So it seems that I need to send domain user credentials which I try below.
I have IIS security set to Digest. The code below was suggested on this post:
http://forums.asp.net/p/1050587/1862246.aspx#1862246
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load<br />
Dim serviceproxy As New WSBus.ServicesBusWebService()<br />
Dim userCredential As NetworkCredential = New NetworkCredential("username", "password", "domain")<br />
Dim credentials As CredentialCache = New CredentialCache()<br />
credentials.Add(New Uri(serviceproxy.Url), "Digest", userCredential)<br />
serviceproxy.Credentials = credentials<br />
serviceproxy.PreAuthenticate = True<br />
<br />
Dim response = serviceproxy.HelloWorld() 'BREAKS HERE<br />
lblMessage.Text = response<br />
End Sub
Any help will be greatly appreciated!

hi,
can anybody Pls. guide me how can i disable the option of saving/copying images on its right click in asp.net webforms.

I would say .. "Don't do that! man" it is just wasting time and money..
There are a lot of people who has already tried to achieve this but there are always some sorts of hecks for copying images.
Let me tell you some attempts that people tried to protect their images of being copied
#1. Disabling right-click.
Everybody knows this is useless.. Don't forget "Save as" or "Firebug"
#2. Showing the transparent images over the actual image.
It can trick the normal user but not for advanced user. There are very powerful tool (eg: Firebug) that can manipulate the HTML DOM in very easy way.
#3. Using third-party tool for protecting images.
If you google a lit bit, you will see a lot of ads mentioning that they can protect yours images (even HTML code). I have tried them some time back. Those tools are NOT good enough.
#4. Embedded Object(Flash or ActiveX)
Using flash might be the best way (so far) for image protection. But one thing, there are some tools or firefox extension (eg: Download Helper ) that can easily download .flv (flash) file. so, peopele might not able to copy the image but they can still copy the *.flv file.
So, don't do that.. man... Of course, this is my own opinion. so, you may wanna listen what other people say.
